Title: Document size detecting device
Inventor: NAKAGAWA JUN
IPC: H04N1/04
Filed: 1990-11-16
Abstract: PURPOSE:To remove the noise components due to the stain of a copy or the like which exists in the peripheral region of a document by integrating the image signals both in the main scanning direction and in the auxiliary scanning direction. CONSTITUTION:The image data of document information being output from an A/D converter 22 are alternately stored in a memory A, 24a and in a memory B, 24b by one run of scanning. When the number of scanning increases and reaches the tenth scanning, the image data for one run stored in the memory B, 24b, are shifted to a memory 26, and in the subsequent eleventh scanning, the image data for one run stored in the memory 24a are transferred to the memory 26, and they are added to the image data already stored, and the procedure is repeated until the sixtieth scanning is reached. On the other hand, the integrating operation to a memory 31 is repeated within the maximum scanning region. Then, the integrated values both of the memory 26 and of the memory 31 are read, and the number of picture elements at the time the read-out rate of change first exceeds the threshold value is made to be the position data of the point of change. The width of the document is calculated by using these numbers of picture elements.

Title: Method and system for controlling moving body
Inventor: IGARI HIDEO
IPC: B23Q41/02
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for the moving body to reach a movement destination after an allocation request is issued by moving the moving body to an area wherein the issue frequency of the allocation request is high when the moving body stays in an area where the issue frequency is low. SOLUTION: When an automated guided vehicle which exceeds a set time is detected, a carrier information storage means 13 is accessed to acquire position information of the detected automated guided vehicle and when the vehicle is switched to a stand-by state in an area wherein the issue frequency is low, a central processor 11 issues a movement stand-by indication to this vehicle. For example, the central processor 11 accesses the carrier information storage means 13 to select an area the issue frequency of the allocation request is larger than a prescribed value and the number of vehicle in a stand-by state or stand-by movement state is small as compared with the issue frequency, and specifies this area to issue the movement stand-by indication.  Thus, the central processor 11 moves a vehicle from an area wherein the operation rate of the vehicle is low to an area wherein the operation rate is high and many vehicles are needed and places it in a stand-by state.

Title: Data processor
Inventor: YANAGIUCHI SHIGENOBU
IPC: G06F15/02
Filed: 1986-12-27
Abstract: PURPOSE:To actuate a data processor in the final working mode of the preceding application by storing the working mode set right before a power supply is switched off at the end of application and initializing said memory mode when the power supply is applied next. CONSTITUTION:When a power supply switch 5 is pushed and turned off, the working mode set right before the switch 5 is decided. Then it is decided whether an executing action mode is set or not as long as an arithmetic operation mode is not set. If not, it is decided whether a programming action mode is set or not. When the executing action mode or the programming action mode is detected, this detected mode is stored in a working mode area 29. The switch 5 is turned on again after a cut-off state of the power supply lasts for a prescribed period of time. Thus the preceding working mode is read out of the area 29 and this mode value is used as the initialization value.

Title: Air-fuel ratio control device of engine
Inventor: ISAMIGAWA FUMIO
IPC: F02D41/14
Filed: 1988-12-09
Abstract: PURPOSE:To eliminate hunting at normal times and prevent delay in response by measuring the cumulation parameter after judgement whether the invertion of air fuel ratio is small, middle, or large, comparing the result with a command value, and correcting the judging reference for small, middle, and large or the integral constant. CONSTITUTION:A measuring means 5 measures the deviation of the actual air fuel ratio sensed by a sensor 4 from its command value, and a calculating means 11 calculates the amount of feedback correction. After a judging means 6 judges that the large/small relation of the two values of air fuel ratio has inverted, a means 9 judges whether the integral parameter given by a measuring means 7 is small, middle, or large with respect to the judging reference given by a setting means, and if small, a setting means 10 sets a small integral constant, if middle a large integral constant, and if large, again a small integral constant, and thereby the fundamental injection amount is corrected. The integral parameter after judging small/middle/large is measured by a means 13, and upon comparison with the command value at a means 14, the judging reference for large/middle/small or the integral constant shall be corrected by a means 15. Thus response delay likely at transient can be prevented without causing hunting at normal times.

Filed: 1994-12-15
Abstract: PURPOSE: To acquire a semiconductor substrate for foreign matter control which does not generate fine irregularity in its main surface in a cleaning process by making a silicon substrate formed by a float zone method a semiconductor substrate for foreign matter control. CONSTITUTION: A semiconductor substrate for foreign matter control is formed of a silicon substrate formed by a float zone method. That is, a silicon substrate 2 manufactured by a Czochralski method is prepared. A crystal defect 3 caused in a single crystal manufacturing process exists inside the silicon substrate 2. Then, an epitaxial growth layer 4 of silicon is deposited on a surface of the silicon substrate 2. Crystal defect which depends on single crystal manufacturing process does not exists in the epitaxial growth layer 4. However, fine irregularity 5 is formed in a main surface of the epitaxial growth layer 4. Therefore, flatness is realized by performing mirror surface polishing for a main surface of the epitaxial growth layer 4.

Abstract: PURPOSE: To eliminate the need for an anode or a cathode configuration part or additional hole for forming a gas tank for reduced cost and size by providing an electrode means so that an electric excitation signal is capacitively combined to a cavity by a swell forming the cavity. CONSTITUTION: During use, cavities X-Y and Z are filled with gas containing laser, and an RF signal is applied to an electrode.
